China's nano-core technology has made major breakthroughs in many areas of innovation
Beijing, June 14 (Reporter Wu Yuehui) The Chinese Academy of Sciences' strategic pilot technology project “Focus on transformative nano-industry manufacturing technology focus†announced on the 13th in Beijing that after 5 years of collaborative research, the company will specialize in long-term power lithium batteries and nanometers. A series of nano-core technological innovations have been formed in the fields of green printing, nanocatalysis, health diagnosis and treatment, and drinking water, attracting and stimulating social capital investment of more than 5 billion yuan.
In terms of long-term power lithium batteries, a number of battery cells developed specifically for energy use have an energy density of 300 Wh/kg or more, ranking the world's advanced level. Battery pack integration optimization is currently underway to prepare for loading demonstrations; Lithium battery key materials have entered the pilot phase, and more than 30 batteries and electric vehicles have been supplied and formed a cooperative relationship, initially forming an industrial impact; in a new generation of high-energy density lithium-ion battery positive and negative materials, solid state The batteries, lithium-sulfur batteries, and high-level power battery failure analysis technologies have achieved a lot of original results, laying an important foundation for the development of the next generation of power batteries in China.
In the field of nano-green printing, researchers have broken through the world-famous photolithography technology ideas, developed nano-green printing plate making technology, broke through the traditional electrolytic oxidation process route, and built the world's first non-electrolytic oxidation process 6 million square meters Nano-green base demonstration line; breaking through the international difficulties of water-based inks used in plastic packaging and printing, achieving key breakthroughs in green water-based plastic printing inks; solving the high-risk wastewater discharge from plate-making processes, electroplating waste liquids/waste residues from plate base production at the source Historical problems such as VOC emissions have formed a complete green printing industry chain technology including “green plate, green plate, and green inkâ€.
In nano-health technology, the "nano-health technology" has been successfully applied to the development of in vitro diagnostic products and nano-pharmaceutical formulations. Specialized in the research and development of a number of key technologies in in vitro diagnostics with completely independent intellectual property rights. Among them, the inflammatory nanofluidic immunoassay chip, which combines three inflammatory markers, can quickly distinguish between bacterial and viral infections, determine the stage of infection, and provide scientific and effective antibiotic use. In addition, the development of a new "tumor catcher" technology based on high-affinity magnetic particles - peptide nanomaterials, to achieve efficient enrichment and detection of circulating tumor cells, product performance is significantly higher than the same type of product at home and abroad. In the area of ​​drug research and development, a number of initial research and development of nano-pharmaceutical preparations have been completed, and some samples have entered the clinical approval process.
In the development of modern high-tech industries, standards play an increasingly important role. Focusing on the revision of key standards and specifications for the industrialization process of nano-manufacturing, the special project led the formulation of 8 ISO/IEC international standards (2 have been issued and implemented, 6 are under development) and more than 30 national standards, covering nano-energy storage materials. , magnetic nanomaterials for biological enrichment, oxide nanomaterials for catalyst supports, etc., involving methods such as thermogravimetry, infrared, and fluorescence spectroscopy, and formulating a series of nanotechnology health environmental standards, improving the standardization level of the nano industry in China, enhancing China's discourse power in the field of nanotechnology international standards lays the foundation for the healthy development and international trade of the nanometer market in China.
In addition, methane anaerobic olefins and aromatics technology, successfully constructed a lattice-bound single-iron center catalyst, controlled dissociation of methane molecules on the surface of the catalyst, direct activation of methane and directed conversion, and cracked the methane selective activation The century-old challenges in the field of chemistry have opened up new avenues for the efficient and clean use of carbon-based resources and have formed significant influence in the international academic community and industry.
"Analytic technology of transformative nano-industries" focused on the A-strategic technology pilot project was passed on April 25th, 2013 and started implementation. Targeting key scientific and technological issues that China urgently needs to solve in such fields as energy, advanced manufacturing, and population health, the company has systematically deployed 17 research and development tasks in eight sectors including power lithium batteries, green printing, nanodevices, and in vitro diagnostics.
